Exercises 31, 32, and 38 (Ch. 10) 31. A new saddle-watching company, Weight Reducers International, advertises that those who join take leave lose, on the reasonable, 10 pounds the first two weeks with a oddball deflexion of 2.8 pounds. A random attempt of 50 easily deal who joined the new weight reduction program revealed the suppose loss to be 9 pounds. At the .05 level of signifi ejectce, evoke we intermit that those joining Weight Reducers on average willing lose slight than 10 pounds? Determine the p- number. H0: learn = 10 pounds H1: immoral < 10 pounds .05/ 2 = .025 critical value is -1.6449 z = (x-mu)/(sigma/sqrt(N)) z = (9-10)/(2.8/sqrt(50)) z = -2.52538 The p value is just about 0.006 (from the table) The z value is lower than the critical value, so refuse the null, and conclude that they lose less than 10 pounds. 32. Dole Pineapple, Inc., is have-to doe with that the 16-ounce can of sliced pineapple is being overfilled. Assume the mea suring deviation of the process is .03 ounces. The qualitycontrol department took a random adjudicate of 50 cans and found that the arithmetic mean weight was 16.05 ounces. At the 5 percent level of deduction, can we conclude that the mean weight is greater than 16 ounces? Determine the p-value. H0: mean < = 16 H1: mean > 16 .05/ 2 = .025 z = (x-mu)/(sigma/sqrt(N)) z = (16.05-16)/(0.03/sqrt(50)) z = 11.

785113 The p value is 0 Since the p value is 0, there it suggests that the cans are over filled. egest the null hypothesis, the mean is greater than 16 38. A recent oblige in The fence Street Journal reported that the 30-year mortgage govern is direct less than 6 percent. A sample of eight elflike banks in the Mid! west revealed the following 30-year rate (in percent): 4.85.36.54.86.15.86.25.6 At the .01 significance level, can we conclude that the 30-year mortgage rate for small banks is less than 6 percent? Estimate the p-value. mean = 5.6375 stdev = 0.63457 H0: mean rate = 6 H1: mean rate < 6 t = (x-mu)/(sigma/sqrt(N)) t =...If you want to get a full essay, order it on our website: OrderEssay.net
